摘　　要：为提高Revit到MIDAS/CIVIL模型转换效率,基于Revit平台的Revit API技术,借助Visual Studio 2019平台上的C#语言实现Revit模型信息提取程序的二次开发,获取Revit中桥梁模型所含的几何参数、弹性模量、泊松比、容重、密度、阻尼比等模型信息,并利用二次开发的MCT文件生成接口程序形成MCT文件,实现模型由Revit到MIDAS/CIVIL的直接转换,并以辽河大桥主桥为例对该模型转换方法的有效性进行了验证.结果表明:二次开发的Revit模型信息提取程序可以准确地将Revit模型信息传递到MIDAS/CIVIL结构分析模型中;开发的MCT文件生成接口程序可以实现模型由Revit到MIDAS/CIVIL的高效率转换;提出的基于Revit与MIDAS/CIVIL的桥梁结构模型转换方法在实际工程应用中具有较高的有效性.In order to improve the efficiency of the conversion from Revit to MIDAS/CIVIL model,by using the Revit API technology of the Revit platform and C#language on the Visual Studio 2019 platform,the secondary development of Revit model information extraction program was implemented to obtain the model information such as geometric parameters,elastic modulus,Poisson’s ratio,bulk density,density,and damping ratio.Then,the MCT file was formed by using the interface program generated by the secondary development MCT file to achieve the direct conversion of model from Revit to MIDAS/CIVIL.The validity of the model conversion method was verified by taking the main bridge of Liaohe Bridge as an example.The results show that the secondary development of the Revit model information extraction program can accurately transfer the Revit model information to the MIDAS/CIVIL structural analysis model,and the developed MCT file generate interface program can realize the efficient conversion of the model from Revit to MIDAS/CIVIL.The proposed model conversion method based on Revit and MIDAS/CIVIL exhibits a favorable availability in practical use.
